One in four of the top 100 online retailers are travel companies according to a recent survey.

Internet research company Experian’s Hitwise Hot 100 is an annual survey that rates websites by how many visitors they attract. This year, it showed that the budget airlines had by far the most popular travel-related websites.

Four years ago only 23 of the top 50 e-retailers had high street shops, this year the number has grown to 33 showing that although much has been written about the negative impact of internet retail on the high street, there are still many companies investing in stores.
